ABSTRACT
In order to ameliorate the prognosis of patients in burn disaster, national emergency medical rescue expert teams are usually dispatched to incident areas. This article discusses the major work and challenges of the medical rescue expert teams using example of rescuing gas explosion accident in Hangzhou in last few days and author′s personal experience of previous mission. The foremost mission of medical rescue expert teams is to provide feasible strategic advice for burn disaster rescue and pivotal critical care support. The medical rescue expert teams always begin their work in hospitals lack of experience in disaster rescue. According to the characteristics of"7·21"Hangzhou gas explosion accident, the medical rescue expert teams focus on reassessment of the severity and hidden injuries of all patients, referral of patients according to the homeostasis status in patients with different severity, developing medical safety strategies, medical-related public safety strategies, and nosocomial infection control measure for rescue work. Furthermore, the medical rescue expert teams join the treatment for some critically ill patients and sudden emergency cases. The main challenges of medical rescue experts faced are accumulation and improvement of personal medical skill and powerful psychological endurance. Psychological counseling can play beneficial role in rescue group. In addition, establishing coordinated relationship among national emergency medical rescue expert teams, local administration, and local medical group shall be beneficial to disaster rescue.

ABSTRACT
To explore the optimized dispatch of the rescue resources based on the mastered resources informa-tion. The objective function was set as the shortest rescue time, and 0-1 programming models were established and solved for the conditions that the number of medical rescue units was more or less than needed by the missions. In the two conditions, the model's calculated results were both optimal, and could be used to obtain the optimal dispatch solutions while the medical rescue time was the shortest. The 0-1 programming model can be effectively used to optimize dispatch strategy for medical rescue team.
ABSTRACT
Objective To apply computer simulation technology for simulating the emergency medical rescue of different conditions and optimizing the rescue strategy and resource allocation. Methods Firstly, according to the characteristics of the arrival of the wounded and the state of injury, four alternative strategies were formulated and simulated. Secondly, the optimal strategy was determined by waiting time of the wounded and the working intensities of rescue unit. Finally, the reasonable suggestions for the rescue strategy and rescue force allocation were put forward by simulation analysis of the relationship between the arrival rate of wounded and the number of rescue units. Results First-leave-first-served and the select-units strategy could effectively reduce the waiting time of the wounded and the working intensity of the rescue unit. When the arrival rate of class A(B) of the wounded increased, the total number of rescue units increased at the same time under the premise of meeting the requirements of the medical rescue, with the number of A(B) rescue units increasing more rapidly. Conclusion By simulating the emergency medical rescue process using different strategies, the optimal rescue strategy can be determined; the number of the rescue units is closely related to the arrival rate of the wounded; estimating the arrival rate of the wounded and the average treatment time can provide reference for rescue force allocation.
ABSTRACT
BACKGROUND: Earthquakes, floods, droughts, storms, mudslides, landslides, and forest wild fires are serious threats to human lives and properties. The present study aimed to study the environmental characteristics and pathogenic traits, recapitulate experiences, and augment applications of medical reliefs in tropical regions. METHODS: Analysis was made on work and projects of emergency medical rescue, based on information and data collected from 3 emergency medical rescue missions of China International Search and Rescue Team to overseas earthquakes and tsunamis aftermaths in tropical disaster regions Indonesia-Aceh, Indonesia-Yogyakarta, and Haiti-Port au Prince. RESULTS: Shock, infection and heat stroke were frequently encountered in addition to outbreaks of infectious diseases, skin diseases, and diarrhea during post-disaster emergency medical rescue in tropical regions. CONCLUSIONS: High temperature, high humidity, and proliferation of microorganisms and parasites are the characteristics of tropical climate that impose strict requirements on the preparation of rescue work including selective team members suitable for a particular rescue mission and the provisioning of medical equipment and life support materials. The overseas rescue mission itself needs a scientific, efficient, simple workflow for providing efficient emergency medical assistance. Since shock and infection are major tasks in post-disaster treatment of severely injured victims in tropical regions, the prevention and diagnosis of hyperthermia, insect-borne infectious diseases, tropic skin diseases, infectious diarrhea, and pest harms of disaster victims and rescue team staff should be emphasized during the rescue operations.
ABSTRACT
The battlefield rescuing unit of the current model is always restricted by some factors such as regional environments in wartime rescuing action and peacetime disaster relief, which can lead to failure of following and deploying action, so that wounded persons can not be rescued at the first time. Aiming at the special circumstances, a forward first-aid unit composed of five doctors and nurses should be established to give emergency medical rescue with rescuing emergent equipments and medicine packed in portable packages such as portable respiring machine, defibrillator and oxygen device at the battlefront. In this way, success rate of rescuing wounded persons would be increased obviously, while mortality rate and deformity rate would be decreased greatly.
